ilgpl'ieeon filed February' Be it known that. l, fiii'oiie'rix L. @Ame MAN, a citizen oi.- 'he ii'iiiieci Sintes, and :i resident of East reiige, in the county oi" Essex and Siete or' lew Jersey, have invented certain new ane useful lmprovemeni: in Primary Batteries, of which the Yfollowing is a specification.

My invention relaies ge'eeriiiiy to iinjorov'ements in primer?,r or ioiieio batteries., im more particularly to aha-e ein, in which the negativeelecrode consi .fe of i plete of @Kid of Copper, or other riejpolnrizirig; n.55 rit prop orly molded mici agglomereiei, imei the pesitive electrode of which eohsisis of e pierre or plates of zinc. i

My invention ihoiuries improvemenfs oh the structure desci iii ihe paient to Eher. G. Dodge, No. y w rmiieri July 22S. 1908. vln primary on le de scribed in this patent7 both the positive- :md negative elements are supported by one frame or hanger including m imfertei ition, which is seeurei to A im' cover by e holt and mit., Wrerlioy eiee trocles and their supporting freine or imager may be easily removed es e unitary eiruoure for :my desired purpose such as cleaning or renewals. in batteries oi' his ftype iheholi provided with :1 'we ige shaped heed Wh 1 is drow-i1 into enge meut, wiihtlie wells of, the hanger by th" hat when ihe electrodes and their supper ogg 'frame or hanger secured in pince fio die jar cover. uiii/Them, however, the hui, ifi removefi rom. the holt, the letter is no ioriger helo. iii. piace 'in the henger and is lisible io drop out of place, thereby causing inconvenience.

rEhe object oi my invention is io provide an efficient connection between the bolt, or other suspension means and the support-ing frame or henger or other supporting strueture, whereby the holt or other snepensiou means is held in place iii the supporting frame or henger or other supporting saruehire, when the electr-mies and their supporting structure are removed from the jar e nier; and, furthermore, io provide such o. connection. that as the mit is tightened up to draw the supporting structure into place beneath the jar cover, the electrical and me ohanieai Contact between the holt head and Speeioaton of Leters Patent.

in seoion of :i portion of :L ii'ip; my invention; Fig. 2 is i siructure shown in Fig. thereto; 'ig. 3 is e vertical in the lihe '-f yin Fig. l and e" certain ijieieiis of e nisiirimtion; and a pian View of the boli head and a on of the :ir or hzmeer.. and show "liierl ii'mfm. of opening for the bolt .e :mil henger. i. g; io the drawings, the top or. @over ei' the battery jar is shown at 1,.

The numeral indicates a .i1-ame or'hanger preferably @meti-noted of a strip of sheet roiii'per or chopper pated iron or steel, the of sfr-i1', ipheing turned up to such en ement oe to lie riot zigeiosl; ille here?. erle oi the iii retire eleorode piate The l pre. ably oi copper ozicl. The oss section of the wer 2 is channel shaped es sl'xoivh in 'Fig 1. 3 :incl 4. The heviger is preferably given the 'form of nn Pieri U, i' le two .firms or dependingpora 'is of which hold the edges of ih@ negaiire plaie ifhe seid plaie 3 fits into the che meis of the henger 2 and is held in said henger by any suitable supporting means, es :For exemple, by rips L formed in The lower ends oi.I the depending firms oi the hanger 2. The plete 3 is also 'further clamped in he henger by a horizontal cross piece or bridging member 5 preferably of similar imirerisll eind Crossfire-.tion io ihe hanger 2, euri secured ot either end to the sifles oi the henger hy end projections 6 which extend tlirough openings 8 in the hanger and are bent into clamping position` against the outside of the hanger. The sides of Jrhe bridging member 5 faire provided :with depending lips 9 having irapezoirial openings therein registeringlwiiih e similar operi# infr on the plate 23.

T he zine or positive electrode plates of the Figure i. is :i side battery indicatechat- 1G are secured to an insulating block or `bloelrs ll and to the bridging-'member 5 by a suitable bolty l2. ,Thusnthe zinc plat-es .aresupported from the bridging member', and the battery plates and their supporting trarne form a unitary `structure adapted tol be'supported from the jar. cover by asingle bolt or other suspension means.

las a means for supporting the tranne and the battery plates from thejar cover, have used a suitable bolt 13 which is prejierably screw threaded..v The bolt 13 is provided with a. Wedge shaped head le, the Wedge faces thereof preferably having one oi? 'more grooves or in lon itudinall of the bolt. rlhe hanger '.lhanger as is indicated 17 in 2, which, as hereinbetore stated, is channelI shaped in cross section, is proyided With an opening 16 in the base o lthe channetl 'The opening may be round, as shown in Fig. e, or elongated,las shown il Fig. l,- v suitable shapeu ln assembling the parts the bolt 13 is passed through the opening, l5 so that the stern oit the bolt. extends through the opening 16 and the Wedge faces are in engagementy withy the Walls oft the channel [shaped hanger 2. :ret'erably a ,slight clearance is lett between he shoulder et the -bolt head and the base ot the channel sh Eig. 3, for a purpdse hereinafter set orth.l llhe metal ot the hangen particularly et the Walls thereof, is then upset over and around the sides, into the groores, oye the base ot the bolt head L.- shown in l? method such as by s and the portion of the thereto, after assembly as descr to compression between suitably sha}y ed dies. n this manner an eflcient mechanical an' electrical connection between the bolt a c thehanger is secured, and the bolt is hele in place by the metal of the hanger upse around it. The bolt then'becomes apart of a uhitary structure including the battery plates and their supporting iframe. his structure may be attached to the battery jar cover l by passing the stein of the bolt Il throughs hole 18 in the battery cor-tr, and drawing the structure into place by means ot a nut 19. On account ot Lhe ight clearance bet-Ween the shoulder ot the bolt head .and the base of the channel shaped hanger Q, the bolt head may be moved slightly With' reference et the hanger when the nut lil t d on the bolt. The Walls of the hanger .itticiently, When necessary, to pera this' movement, but the grip ofv the hangeron the bolt head .is not loosened.; trary, the bolthead is 'wedged more between the Walls ofthe hanger, there.

n-mducing a more edeetiye mechanical lteyrvays l5 termed therey or ot other I tapedl on the con-v electrical connection. i lt is to be noted that the provision of ,grooves or leyways' in 'the boa han ioagauanaliyof uw e011; perm-as the inovenientreferred to Wilthout loosen-v in'g the grip br the hanger on the bolt head.i `llurthe'rmore, it it is desired to detaph the battery plates and tha` supporting l"frame tro n' .the battery jar over, thebolt will be retained in place in the hanger and ready for rfa-attachment to Vtihe jar cover.
